Each channel 54 is defined by a plurality of first sidewalls 55 and a second sidewall 56 . The first sidewall 55 is parallel to the water flow F passing through the water distribution shaft 20 , and the second sidewall 56 is tangent to the water flow F. As shown in FIG. Each channel 54 defines a water inlet 57 at the end of the body 53 , and each channel 54 defines a water spray port 58 at the front end of the head 52 . The size of the water inlet 57 is larger than that of the water spout 58 , and the water spout 58 is eccentrically corresponding to the water inlet 57 . A plurality of the water spouts 58 are radially arranged on the head 52 .

As shown in Figures 11 to 13, the water flow F passing through the water dividing shaft 20 is divided by the several fins 22 and enters the several water inlets 57, the water flow F passes through the first side wall 55 in the forward direction but hits the second side wall 56 . The several second sidewalls 56 are impacted by the water flow F, so that the rotating nozzle 50 rotates rapidly, and sprays out from the water spray port 58 to form rotating water splashes.
